OILER FOR RAILWAY-AXLE BEARINGS.

. SPECIFICATION forming part of Letters Patent No. 414,783, dated November 12, 1889.

Application filed June 14, 1889. Serial No. 314,313. (No model.)

To all whom it may concern:

Be it known that I, THOMAS H. SYMINGTON, a citizen of the United States, and a resident of the city of Baltimore, and State of Maryland, have invented a new and useful Improvement in Oil'ers forAxle-Bearings for Railroad- Cars or Locomotives, of which the following is a complete specification.

Figure l is a longitudinal sectional elevation of a car-axle box, showing the oiler in the bottom thereof. Fig. 2 is a plan 'viewof the oiler when removed from the axle-box.

In the drawings, A represents the end of an axle; B, a box inclosing the end of the axle; O, the bearing-block resting upon the axle and bearing against the inner side of the top of the axle-box.

D is the oiler-box, perforated by apertures (Z (l (Z (Z at thesides and ends for the admission of oil which lies in the bottom of the axle-box.

E is a cover to the oiler-box D, perforated in its top by the small holes 6 e e, distributed over its surface, and having the large circular opening Gin its center. The cover E is bolted to the box D by means of bolts e passing through then1.. In the cent-er of the box is cast a ring d This ring may be perforated laterally with holes for the exit and inflow of oil, or it may be slotted, as shown in Fig. 2, with slots (1 The size of the slots will depend upon the amount of oil which it is desired to throw upon the axle.

F is a cap of a size to fit'in the opening G in the cover E, and provided upon its interior at the center with a circularlug f This lug may be of any desired shape; but I prefer to make it circular. The lug f is made of such a size as to lit snugly into the ring (1 and in operation acts as a plunger working in a cylinder, the ring (Z forming the cylinder.

shape and position of the holes and the effect produced thereby. The holes are constructed as follows: 1

The hole f is vertical while passing through the plunger f but inclined toward the end of the axle while passing through the top of the cap F. The inclination of this hole must be carefully determined in every case in which the oiler is tov be employed, in order that the oil forced from it by the motion of the cap F will be thrown far enough and yet not too. far upon the bearing-surface of the axle.

The hole f is identical in shape with J, except that it is inclined in an opposite direction, so as to throw oil toward the inner end of the bearing-surface of the axle.

The holes f and f are two branches of a central hole f and are inclined away from the axial line of said hole, but in a line parallel to the axle. The inclination of these holes is such as to distribute the oil ejected from them upon the surface of the axle midway between the points at which the oil ejected from hole f and f strike it. The vertical hole f is made of smaller diameter than the hole f and f, for the reason that, being in the center of the piston or plunger, the pressure of oil upon it is gr'eatenthan upon the holes f and f and too much oil Will be forced through it unless it is made smaller than the others, notwithstanding the fact that it divides into two parts before it leaves the cap.

For the effective operation of my device it is necessary that the holes f f f and f should be maintained in aline parallel to the axle. For this purpose, Where a circular cap is employed, the lugs f f are cast upon the sides of the cap, and a guide or guides f f are cast upon the interior ofthe oiler-box D, between which the lug f rests and prevents the cap from turning. This same result might be accomplished by making the cap of any form other than circular or castinga fin upon it which would enter a notch in the cover E. The lugs f being on the lower edge of the cap F, serve to prevent the cap from beingthrown out of the device by an unusual expansion of the spring.

I am aware that a device somewhat similar to mine was patented by William Painter in 1871; but my invention differs very materially from his in accomplishing a result of which his is incapable.

The operation of the device is as follows: The oiler, secured together as a compact whole by the bolts 0 6 is placed in an axlebox beneath the axle. Oil is then poured into the box to a sufficient depth to about half submerge the oiler. \Vhen the car or loco motive upon which the device is employed is set in motion, the heavy cap F,,sustained by a light elastic springf, will reciprocate up and down with the jolting of the axle-box. This will cause the plunger f to be forced into and Withdrawn from the cylinder or ring (1 and the oil contained in said cylinder to be forced through the holes f, ffif, and f in a line parallel to the axle upon the surface, thereby distributing upon it fresh oil with every jolt of the truck.

Having thus described my invention, what I claim,and desire to secure by Letters Patent, 1s

1. In an axle-oiler, the combination of a cylinder containing oil with a plunger reciprocating therein by the jolting motion of the vehicle, said plunger being sustained by a flexible spring and being perforated with two or more holes in line with the axis ofthe axle and inclined,respectively,toward the front and rear end of the bearingsurface of the axle, substantially as described.

2. In an axle-oiler, the combination of a cylinder containing oil, said cylinder being perforated transversely to permit the escape of superfluous oil, with a plunger reciprocating therein by the jolting motion of the vehicle, said plunger being sustained by a flexible spring and being perforated with two or more holes in line with the axis of the axle and inclined, respectively, toward the front and rear end of the bearin -surface of the axle.

3. In an axle-oiler, the combination of the cylinder containing oil with a plunger reciprocating therein by the jolting motion of the vehicle, said plunger being sustained by a flexible spring and being perforated with two or more holes in line with theaxis of the axle and inclined, respectively, toward the front and rear end of the bearing-surface of the axle, and means for preventing the rotation of the plunger and maintaining the parallel between the line of holes and the axle.
